It has been almost 4 yrs since I built my computer so please bear with me as I have not been up on the newest trends.
I unplugged my tower to clean behind it and straighten out the wires. When I plugged everything back in the computer would not power up.
After numerous tries I left it alone for a few hours. Upon trying again it started up. I did not turn off for a few days. Upon restarting the computer it would power up but windows would not start up. It would hang up and not load windows.
After researching online I unplugged all USB plugs except mouse & key board. This allowed the computer to start up and load windows (XP). After plugging in all USB plugs everything would work but the printer.
After shutting down computer and restarting it would not power up. I checked PSU ok with paperclip jumper.
After looking on here I saw the suggestion about installing the reset wires to the power pins on the MB. This worked and computer started and windows loaded. I wanted to re-install windows XP with clean install but when I shut computer down it would not restart.

Do you think the issue is with the power/ rest buttons (or wires) or with MB pins for power wires? The MB is getting power (light on). When PSU jumped with DVD drive & fan plugged in they turn on.

Thank you
Brian

Try using the power switch on the back of the power supply and see if it will then power up.

Aside from that, pull it apart and test. There is a guide here > http://www.techsupportforum.com/forums/f255/how-to-bench-test-troubleshoot-your-system-171424.html

Not likely.

But again, try powering off the power supply (there is an off/on button on the power supply)...watch the motherboard light go off, turn it back on, and THEN use the front panel switch.

If it will turn on every time after turnin the power supply off/on first, the power supply is bad.

Remove everything from the motherboard except for the cpu and heatsink. Test again. It should power up and give BEEP / ERROR codes. If it doesn't power on, its a motherboard or power supply fault.
